Suzy Silverstein, 54, of the Florence section of Northampton, passed away on Sunday. An obstetrician, she delivered thousands of babies in the Connecticut and Pioneer valleys. Born in Philadelphia, she graduated from the University of Pennsylvania in 1979 and attended New York University for both medical school and residency. She practiced for many years with Hampshire OB/GYN in Northampton and for the last few years was on staff at Baystate Medical Center. She was an avid quilter and seamstress, and was fond of making baby quilts for newborn babies of friends. Baking was a passion, especially cookies and small pastries.
